Description

Technical Field

[0001] This utility model relates to the field of proportioning analyzer technology, and in particular to a multifunctional proportioning analyzer. Background Technology

[0002] The testing instrument's functional box, based on the gas mixing and proportioning unit, adds gas content analysis, flow controller, outlet pressure control, and pressure display. The use of gas shielding in welding processes is increasing. In industrialized countries with high levels of mechanization and automation, simple CO2 gas as a shielding gas is no longer sufficient for welding requirements. Mixed gas shielded welding offers significant improvements over simple CO2 gas shielded welding in terms of weld appearance, internal weld quality, penetration, welding speed, and spatter generation. Currently, with the improvement of welding technology and automation levels in my country, and the increasing demands for welding quality from various industries, the application scope of mixed gas shielded welding is constantly expanding. The mixing and proportioning unit is produced to meet this market demand and is already widely used in shipbuilding, steel structures, automobiles, motorcycles, teaching laboratories, electronics, and other industries.

[0003] In the field of gas analysis instruments, standard gases are an important means of calibrating and standardizing the measurement results of gas analysis instruments. When calibrating or standardizing instruments, different concentrations of gas are required. The amount of each concentration of standard gas needed is small, but the corresponding concentration of standard gas needs to be provided for each calibration point. Purchasing standard gases produced by specialized manufacturers for each calibration point is not only costly and uneconomical, but also results in significant waste.

[0004] Patent document CN215866605U discloses an automatic standard gas mixing device for a gas analyzer. The device includes a housing; three mass flow controllers, all installed within the housing; a programmable logic controller (PLC) mounted on the housing, with the three mass flow controllers electrically connected to the PLC; and a display mounted on the housing, electrically connected to the PLC. This invention provides an automatic standard gas mixing device for gas analyzers that allows for the automatic mixing of standard gases simply by purchasing a suitable industrial gas source, and is characterized by its simple structure and economical operation.

[0005] The aforementioned gas analyzer requires multiple gas cylinders carrying different types of gases to be connected to the analyzer via gas delivery pipes during operation. However, standard industrial gas cylinders, due to their cylindrical structure, have a relatively high center of gravity and require external fixing devices for restraint during normal operation. Otherwise, they are prone to tipping over under equipment vibration or stress on the gas delivery pipes. Furthermore, the analyzer's multi-gas interface uses a parallel layout, which can easily cause the pipelines to become tangled and intertwined when 3-4 sets of gas delivery hoses are connected simultaneously, reducing work efficiency and posing safety hazards.

The top of the analyzer body 1 is provided with a touch-screen display 8, an indicator light assembly, a connector assembly, and an output flow meter 17. A control system module is installed inside the analyzer body 1. A gas cylinder auxiliary assembly is installed on one side of the analyzer body 1. The input gas cylinder and gas collection bag are placed on the gas cylinder auxiliary assembly. The analyzer body 1 can achieve arbitrary combination of any two gases (argon, carbon dioxide, and oxygen) or any three gases (argon, carbon dioxide, and oxygen). Gas is input through multiple inlets and enters the analyzer body 1 for gas mixing. The gas flow rate is controlled by the control system module to achieve gas mixing. During the gas mixing process, multiple gas cylinders are fixed inside the gas tank and secured with elastic fixing straps 27 to ensure the stability of the gas cylinders during the gas mixing process.

[0026] As a preferred embodiment, the control system module includes a PLC control system 18 and a flow controller 22 installed in the analyzer body 1. Three pressure transmitters 21 are connected to the input of the flow controller 22, and these transmitters are respectively connected to an argon inlet 2, a carbon dioxide inlet 3, and an oxygen inlet 4.

Users input parameters into the system through the touch screen. The control system module coordinates the collaborative work of the flow controller 22, pressure transmitter 21, mixer 23, and solenoid valve 20 through the PLC control system 18. Argon, carbon dioxide, and oxygen enter the system through independent input ports. The pressure transmitter 21 monitors the input pressure of each gas in real time and feeds it back to the PLC.
